Why the underwriting tiers diverge, and the liquid buffer each breed warrants before acquisition.
Wide genetic diversity from unplanned, multi-line breeding gives this cat the lowest hereditary disease burden of any cat breed, leaving only common, largely preventable conditions.
Tartar and gum inflammation build up over years in any cat, and this is the single most common reason a domestic shorthair ever needs a dental procedure.
Free-fed indoor cats gain weight readily, and the resulting excess weight is the top risk factor for developing feline diabetes.
Cats sourced from shelters or multi-cat environments are more likely to carry a viral respiratory infection at adoption, which can flare again under stress.
Coat load, energy, and temperament shape boarding, grooming, and handling costs beyond the medical ledger.
Adjust the compounded annual CPI. Veterinary clinical services have trailed near +7.8% YoY; the pet-care basket sits lower.

A well-documented cardiomyopathy predisposition combined with a known clotting-factor disorder in some lines creates recurring cardiac and surgical-risk cost above breed-average.
One of the most consistently reported heart conditions in the breed, thickening the heart wall and often managed with lifelong medication once detected.
A rare inherited clotting-factor deficiency documented in British Shorthair bloodlines that can turn a routine surgery into a higher-risk, higher-cost procedure.
The breed's stocky, round-bodied build gains weight readily on free feeding, adding joint stress and diabetes risk over a long lifespan.
